Howell, T.R. 1950 S. varlus ssp. 29 mi. SW of Princeton, f., British Columbia May 11 (cont'd) looks around, then glides off with a rattle. 7:55 - Repeated tattoos from the same place they were heard at 7:17. 8:00- The tattooing bird, a ♂ nuchalis, flies over to a dead tree about 60 yds from the R-n. nest site. What I take to be both are there - much squawking, "crest" raising. R. chases the ♂ n. for a few feet at a time; Fn follows. A. tattoos; Fn answers; ♂ n. silent. ♂ n. flies over 50 yds, to what I presume is his territory: in a moment R. follows. Squawks - I believe ♂ n. now chases R. back to within about 80 yds of "his" nest site, to a balsam. Then they go lower to a dead stub, and R. chases ♂ n., who flies back about 50 yds to his own territory, and begins to tattoo. R. goes to the balsam and begins feeding. It has been used before, and has long streaks of yellow sap running down it. I cannot be absolutely certain of the sexes of the above birds, but I am as sure as I can be without collecting them. 8:20- R. just arrived at nest, working. The bird has a white post-ocular spot, as a few ruber have occasionally, but almost always F.s. 8:24- yelps; R. keeps on working. 8:25- more yelps; N. to nest from north, alights by R, who keeps on working. N. then off to north, alights low. R. leaves nest, flies by. Both go over to a stump, over the base of which a little stream flows
